Nothing to run from here
Ruah is installed from its publisher's own source and answers where it runs, so this marketplace is not in the path of a single call. There is no address here to send one to, and a panel that pretended otherwise would be showing you an answer we made up. Install it and call it from your own client — the Installation tab has the entry for each one.

What it does
On-device image tools: background removal, compression, resize, crop, AI upscale, metadata removal.
Quickstart
# 1 — add it to Claude Code
claude mcp add --scope user ruah-mcp '--' npx -y ruah-mcp
# 2 — ask your agent for something these tools do
# remove_background, compress, resize and 3 more
Ruah costs nothing on mcprush: there is no plan to choose here, no cap to set and nothing mcprush can bill you for.

Installation
Where are you running it?
Every route below installs the same thing and ends at the same approval screen. This one runs on your machine: your client starts Ruah as a process under your own user, with your files and your network, so the tool surface below is what it can do to your computer rather than to a server somewhere else. Its scan result is on the Security tab — read the surface before you approve it.
Claude Codedeclared by this listing
This is a public server: you run it yourself and this marketplace is not in the path. You need Node.js — the current LTS (24) is the safe choice; npx comes with it. Claude Code registers it in one command; --scope user makes it available in every project. The '--' is in quotes so that PowerShell passes it on.
claude mcp add --scope user ruah-mcp '--' npx -y ruah-mcpReconnect, or start a new session, and the tools appear in the model’s tool list.
Free on mcprush, and it runs from its publisher’s own package: this marketplace is not in the path, so there is no key of ours to hold and no card to add.
What it writes
One config entry your client uses to start the process locally. A local server runs with your file system and your network, which is why it is priced without metering.
What you approve
6 tools, with what each one reads, writes and reaches shown before you agree — the same list on every route above. Read the tool surface.
Tool surface
What the model actually sees. Descriptions are diffed on every release — see version history.
Read from its source code. A server that builds its tool list when it starts can list more tools than this.
Cut the main subject out of a photo and make the background transparent (on-device AI — the image never leaves this computer).
| Parameter | Type | Required | Notes |
|---|---|---|---|
| input_path | string | yes | Image file to process (jpg, png, webp, avif, gif, tiff; heic on macOS). Absolute, ~/…, or relative to the working directory. |
| output_path | string | no | Where to save the PNG. Default: "<name>-cutout.png" next to the input. Existing files are never overwritten. |
Make an image file smaller with little visible quality loss, on-device (same encoders and defaults as ruah.tools).
| Parameter | Type | Required | Notes |
|---|---|---|---|
| input_path | string | yes | Image file to compress. Absolute, ~/…, or relative to the working directory. |
| output_path | string | no | Where to save. Default: "<name>-compressed.<ext>" next to the input. Existing files are never overwritten. |
Change an image's pixel dimensions, keeping its proportions, on-device (same high-quality resampler and encoders as ruah.tools).
| Parameter | Type | Required | Notes |
|---|---|---|---|
| input_path | string | yes | Image file to resize. Absolute, ~/…, or relative to the working directory. |
| output_path | string | no | Where to save. Default: "<name>-resized.<ext>" next to the input. Existing files are never overwritten. |
| max_side | integer | no | Fit inside this many pixels on the longest side. |
| percent | number | no | Scale to this percentage of the original (1–100; to enlarge, use max_side with allow_upscale). |
| allow_upscale | boolean | no | Allow max_side to make the image larger than the original. Default false. |
Cut an image down to an aspect ratio or an exact region, and/or turn it by quarter turns or mirror it, on-device (same tool as ruah.tools/crop: whole pixels moved, never resampled).
| Parameter | Type | Required | Notes |
|---|---|---|---|
| input_path | string | yes | Image file to crop. Absolute, ~/…, or relative to the working directory. |
| output_path | string | no | Where to save. Default: "<name>-crop.<ext>" next to the input. Existing files are never overwritten. |
| aspect_ratio | string | no | Width:height of the result, e.g. "1:1", "4:5", "3:2", "16:9". Keeps the largest centred area of that shape (after rotate). Give this or box, not both. |
| box | object | no | Exact region to keep, in pixels of the input as shown (upright), measured before rotate and flips. Give this or aspect_ratio, not both. |
| rotate | integer | no | Turn clockwise by this many degrees: 90, 180 or 270 (-90 turns anticlockwise). Default 0. |
| flip_horizontal | boolean | no | Mirror left↔right (after rotating). |
| flip_vertical | boolean | no | Mirror top↔bottom (after rotating). |
| format | yes | — | |
| quality | integer | no | 1–100 for webp/avif/jpeg. Default 90, like the web crop tool. |
| lossless | boolean | no | png only: keep exact colours. Default true; false makes a smaller palette PNG. |
Enlarge an image 2× or 4× with on-device AI super-resolution (the same models as ruah.tools/upscale — the image never leaves this computer).
| Parameter | Type | Required | Notes |
|---|---|---|---|
| input_path | string | yes | Image file to upscale (jpg, png, webp, avif, gif, tiff; heic on macOS). Absolute, ~/…, or relative to the working directory. |
| output_path | string | no | Where to save. Default: "<name>-upscaled-x2.<ext>" (or -x4) next to the input. Existing files are never overwritten. |
| scale | no | 2 = twice the width and height (default — quicker, and enough for most images); 4 = four times, for genuinely tiny sources. | |
| format | yes | — | |
| quality | integer | no | 1–100 for webp/avif/jpeg. Default 90, like the web upscaler. |
| lossless | boolean | no | png only: keep exact colours. Default true; false makes a smaller palette PNG. |
Remove hidden metadata from an image before sharing it, on-device (same cleaner as ruah.tools): EXIF (GPS location, camera and device, date taken), XMP, IPTC, comments, embedded thumbnails and extra data such as motion-photo video.
| Parameter | Type | Required | Notes |
|---|---|---|---|
| input_path | string | yes | Image file to clean. Absolute, ~/…, or relative to the working directory. |
| output_path | string | no | Where to save. Default: "<name>-clean.<ext>" next to the input. Existing files are never overwritten. |

ATrust score 96 / 100
Release 0.1.1 · scanned 3 Nov 2026
Two independent axes, because powerful and malicious are different questions. The grade is threat only. The capability level is blast radius, and it is never a penalty on the grade — it is priced as one subtract-only term in the score, where you can see it.

score = clamp(round(threatScore − E_cap − E_ver − E_cov), 0, 100). No model, no opinion, no network call at scoring time: the same methodology version against the same bytes always produces this number, and every line above is a field of the report rather than a summary of it.
What the scan could actually read
A grade is only as meaningful as its coverage, so the scanner publishes its own depth before it publishes its result.

Implementation sourceread

Live transportnot available
Tools were statically extracted from the published source (6 recovered), not enumerated from a running server. Tool-poisoning, Unicode-smuggling, capability and toxic-flow analysis ran on this inferred surface, but a mis-parsed registration could be missed or mis-attributed, so tool-derived findings are capped below “confirmed”. To grade the real runtime surface, scan the running server: --command "npx -y <package>".
Capability — what it could do if the model were manipulated
Tags derived from each tool’s schema and the implementation, not from what the tool calls itself. moderate is the level these add up to.

Toxic-flow graph
The lethal trifecta, checked as a graph rather than as a checklist: untrusted input, a sensitive source and an external sink have to meet before there is a path worth worrying about.
The public result for this release does not print the flow graph, so there is nothing to show here. That is not the same as "no paths were found": what the scan did read is above, under coverage.

This is the first scan of this surface here, so there is nothing yet to compare it against.
Every result on this tab comes from one deterministic pass over the published package — offline, rule by rule, and auditable line by line above. Same methodology version, same bytes, same score.
Release history
Always latest — the install command names no version, so it installs the newest release when it runs; the current release on file is 0.1.1. Pin a release below and the command asks for exactly that one.

Who can review
One review per account, from a signed-in account that does not publish this listing. Nothing else is asked — you can say what you think before you install it. Publishers can reply once per review, and a review can be edited or deleted by whoever wrote it.
Sign in to write one
Any signed-in account that does not publish Ruah can review it, once — before installing it or after. A review from an account that has installed it is marked as one.
No reviews yet
Nobody has reviewed this listing. The rating on the card is the mean of the reviews written here and nothing else, so there is no rating until somebody writes the first — which takes a signed-in account that does not publish it, and nothing else.
